FREDERICK 0. BALL, OF DETROIT, MICHIGAN A SSIGNOR TO BALL & BALL CAR- IBURETOR COMPANY; OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

REATOMIZER.

Specification of Letters Patent.

Patented Oct. 4, 1921.

Be it known that I, Fnnnmuox 0. BALL, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented new and useful Improvements in a Reatomizer, of which the following is a-specification.- .1.

This invention is designed to atomize the liquid which is carried into the passages leading to an explosive engine by reason of the precipitation of the liquid from the mixture or from a failure to fully atomize the liquid in the carbureter usually used. What are commonly known as hot spots have been provided for vaporizing the unatomized liquid but these are subject to certain disadvantages particularly in view-of the fact that the heating of the mixture expands the air and consetquently reduces the quantity which will be rawn into the cylinder with a resultant reduction in power. Withthis invention the liquid which accumulates in the passages is drawn into what I term a re-atomizer, in which the liquid is collected and again subjected to a spraying action of air so as to be broken up and fully atomized. This is accomplished regardless of the temperature of the engine and is also accomplished without addingheat to the air and in its referred form is carried out without adding any moving partsto the apparatus.

The. invention is illustrated in the accompanying drawing wherein 1-1 mark two engme cylinders. As many cylinders as desired may be used, the manifold 2 extending to the different cylinders. The manifold has the inlet 3' with the branches 4 leading from each side of the inlet.

Any desired carbureter 5 may be used. In the one shown 6 marks the mixing chamher, 7 the primary throat leading to the mixing chamber, 8 the secondary throat leading to the mixing chamber, 9 the float chamber, 10 the fuel conduit leading from the float chamber, 11 a metered opening in the fuel chamber, 12 a spray nozzle leading to the primary throat and connected with the fuel conduit, 13 an air opening for in-' troducing air for spraying the liquid through the nozzle 12, 14 a metered opening leading to an intermediate chamber 15, 16 a spra .nozzle leading from the chamber 15, 1, an air opening leading to the chamber 15 and furnishing air for spraying the fuel to the secondary throat, 18 the main throttle at the discharge side of The re-atoniizer is in the'form of a fitting 1 having flanges 22 through which screws 23 extend to secure the fitting to the carbu reter and having a flange 24by means of which it may be secured to the manifold. The re-atomizer is provided with a throat 25 having a very slight restriction and spray nozzles 26 lead into this throat. The spray nozzles lead. from the collecting annulus 27. The collecting annulus has an annular slot 28 extending throu h the bottom of the annulus adjacent to t e wall, the nozzles 26 extending into the restriction formed by the throat have their ends in the path of high velocity and in consequence a very much reduced pressure relatively to the pressure in other parts of the passage. As a result a movement of air or mixture at a very high velocity is induced through the nozzles 26 from the drawing of air-from the annulus 27 and through the slots 28. Any liquid, therefore, that may be accumulated on the walls of the carbureter or the passage above it which is carried along up these walls by the action of the air is caught .air or heat is entirely removed, and thus the carburation which the carbureter is. intended to aflect is not interfered with.

Some liquids may be carried through the throat 25 and some of the mixture which has been previously atomized may be precipitated on to the walls of the passage at the discharge side of the throat 25. I preferably provide, therefore, an annular cup or the mixing chamber, and 20 a throttle con- 7 part of my in socket-2 8 in the upper edge of the throat 25 and connect this cup by a passage 29 with the collecting annulus 27- where it is taken u by the spray nozzles and reatomize i The liquid is also deposited and collects in the depressions in the manifold. In many designs it is diflicult to avoid such .depressions by reason of the requirements of the manifold. The liquid fuel accumulates in these depressions and interferes with the proper functioning of the engine, be-

ing usually finally carried into the engine in liquid form. I prefer to connect such depressions as 30 by means of pipes 31 to a' common pipe 32 leading to a passage 33 communicatlng with the collecting annulus 27 where such liquid is carried through .the nozzles 25 and sprayed in the manner above described. It will be understood that the pressure at the nozzles will be somewhat less than the pressure at the depressions 30 so that there will be a difference in prescepting ingoing liquid from said wall; and

means for driving the fuel from the collec-- tor by a current of gaseous fluid passing through the collector and spraying the liquid into themixture passage.
